Lampard had a ball two feet over the line as the Three Lions where 2-1 down, but Urugayan referee Jorge Larrionda disallowed his effort.
Neuer said: “I tried not to react to the referee and just concentrate on what was happening – it was difficult. I knew it was close.
“Then I saw it on the television in the doping control office and what actually happened. I knew it was tight – probably about two metres.”
